Great game, simple but relaxing. I have a couple of ideas to improve the game: 1) I like to see if I can figure out the minimum number of moves to solve the puzzle. Maybe you could add a move counter and show the minimum number of moves needed as each puzzle comes up. This would add another aspect to the game. 2) It might also be fun to add a time component to the game. Set a reasonable time target for people to solve each puzzle.

Great game!! This game is kind of like "Flow" but better and a little more challenging. I love it!! It is a small app so it doesn't take up much space on your device but there is a lot of content in it. Would highly recommend it to anyone who enjoys killing time on their phones by playing brain games like this.

Power Line This is a very addictive game. Young people & adults will like it. Turning the lights on is fun plus it makes you think.. Starts pretty simple put progresses to more difficult. I enjoy it much. It's great while in a waiting room or any where you Mary be waiting on someone or something. Give it a big thumbs up.

Quickly tedious Idea is initially intriguing, but nothing changes. The puzzles get larger and more time consuming, but never any more difficult to complete. I gave up after dragging my way though 7 x 7 and uninstalled it.

Worse than Logic Puzzle Kingdom I really enjoy this type of puzzle, but Logic Puzzle Kingdom, by Morsakabi has a better veraion of it, as well as other types of puzzles. The biggest advantage of the other app is that you can indicate when you are certain that a piece is correctly aligned. Caution: Logic Puzzle Kingdom does have exclusively larger boards.

Addictive I've played the first 2 hundred levels and so far it gets more difficult but not impossible. You don't have to buy things to get farther. This app is one of my favorite apps right now. Very well done and very fun and addictive!! Excellent app!
